Sellar and parasellar lesions involving the skull base

Abstract

Lesions of the central skull base, most notably the sphenoid bone, commonly originate from the endocranial soft tissues. Although most commonly identified with pituitary macroadenomas, skull base erosion, destruction, and remodeling may be seen with a variety of congenital, neoplastic, cystic, vascular, and inflammatory lesions involving the sellar and parasellar soft tissues.
